Add your gateway entry in the below file

cat /etc/sysconfig/network-scripts/route-<device>
ADDRESS0=xxx.xxx.xxx.xxx
NETMASK0=xxx.xxx.xxx.xxx
GATEWAY0=xxx.xxx.xxx.xxx


This will reflect...

'gateway' is not a per-card setting. Set it in /etc/sysconfig/network

Hey how are you.
I'm a Solaris admin but I have been doing a lot of RHEL administration lately. No matter what UNIX or Linux distro I have work with, the /etc/resolve.conf file is used to point a...

All the Red Hat derivatives that I know (CentOS, RHEL, Fedora) have commands to configure the system. I never used them since I'm more comfortable editing the config files myself, based on templates,...

There's probably a sysconf-* command, but the direct approach would be adding the linenameserver 8.8.8.8 in /etc/resolv.conf.

Yes that is correct.

Normally mail is transferred between mail servers on port 25.
If your system is listening on port 24 you will only be able to send/receive from other servers listening on the same port.

The exact location can vary, but look for a file under /etc named local.start

You can also do it in a users' crontab, with a line like @reboot /path/to/script.sh

ping is extremely straightforward. All it does is send one very specific kind of packet to a specific destination and it either goes or it doesn't.

nmap is a whole suite of stuff. There's not an...

You're right, bridge mode should have direct communication.

If you can ping in both directions, ping is not blocked, so your title's a bit misleading. And if you can ping I think your...

Surprisingly, not necessarily. It may depend on what network arrangement you configured them for. Repeating the same questions doesn't us the information we need to help you.

If you can get it, the arping utility is useful for telling between obnoxious firewalls and actual network problems. A client can't ignore ARP and still communicate over IP, afterall.

Depends on your system, which you haven't said, but most drives these days have either 512-byte or 4096-byte sectors. But the block size isn't quite so relevant these days; the OS talks to the...

"bs" is the block size, not the byte size (a byte is always 8 bits). Reasons you might want to use it:
